Every BEM Electric Motor is a Benchmark of Precision and Quality
BEM Electric Motors Series ML & MH
The BEM ML- and MH-Series Electric Motors combine exceptional performance with compact, energy-efficient design. Equipped with Class H insulation optimized for frequency converters, they ensure durability and reliability. Reinforced inter-turn insulation enables safe PWM converter operation (dv/dt ≤ 5 kV/µs) without costly sinus filters.
Available as induction or permanent magnet motors, they feature either permanent magnet or squirrel cage rotors: PM motors offer a compact footprint, while squirrel cage designs deliver robust versatility for industrial and marine use. Precision engineering and intelligent design make the BEM ML & MH Series a benchmark in efficient and sustainable propulsion technology.
